Adding R/C to your Powerwheels vehicles? Using R/C parts on your Powerwheels?

I am getting ready to mount the steering actuator and LAC once it arrives this week on my RC Jeep project. I am curious if anyone who has used the Firgelli actuators have used a step-down to power the actuator and LAC. This on a 24V setup(2x 12V/12aH). I have a 24V to 12V 5A step-down and the max draw of the actuator is 3A @ 12V. I would rather not run another battery for the actuator and don't see why the step-down would not work but looking to hear other's experiences. Thanks.

Because that actuator probably draws a lot more than 3 amps under load. Likely gonna need a much larger reducer, like this one:

The datasheet looks like it maxes out at 3A. Robotshop specs on the webpage state 4A.

So, a few weeks into a working setup here. I notice when under heavy loads or batteries getting slightly low the actuator becomes sluggish or some times unresponsive. I am assuming the motor draw is causing the LAC to be under powered. Does this sound about right? Only conclusion I can think of. I am using a 24 to 12v 10A stepdown with nothing else powered from it.
